You need to put more information about what type of Dell computer you have and what program is installed. If you have Windows XP you have to do a clean install ... if you have Windows Vista thru Windows 8.1 all you need to do is a system recovery [ f 11] it will reinstall your computer to it's original start up mode. Then you can change your password ... I store all my personal passwords on my cell phone under memo's that way if I forget it there.

This sounds like a BIOS password to me. You are going to have to remove the CMOS battery or find the BIOS/ATMEL chip to remove the password.

There's going to be 3 ways you can do this. The first one is just to remove the CMOS battery, which will work on most pre 2010 laptops. The second is shorting the BIOS chip or some pads, which is common on circa 2010 laptops.

The third is you will have to short the ATMEL chip in the laptop and then boot it to clear the password. However, be warned this can potentially lock the laptop in tampered mode which may brick it. If it doesn't lock you out, it will let you know.

I would suggest the CMOS battery first. It's the least risky of the 3 options.

NOTE: If you are dealing with a ThinkPad, DO NOT REMOVE THE CMOS BATTERY! This will result in the notebook falling back to the SVP. If it has one YOU WILL LOCK YOURSELF OUT OF THE LAPTOP!

Older consumer grade machines typically use CMOS RAM in the BIOS flash chip, while newer machines (crica 2010) store it in the BIOS chip using battery backed CMOS RAM that lives in the BIOS module. This is why you need to mess with the BIOS chip in a lot of these newer laptops.

On the business models, they use ATMEL chips that are usually encrypted. It's been like this since the Dell C series and the 390E for the ThinkPads.

Update

Here is a link on some master passwords. These are all fairly old, so they may not work. If the laptop is newer, the password is based off of a unique number that's tied to that machine via serial number/service tag rather then a single master password.

I think what people are missing here is that it is an Admin account that the password has been lost/forgotten. Without the original password, or a reset disk (that has to be made before you forget the password) you cannot change or create a new password or login method. But iSeePassword would work with you. It can create a bootable USB or DVD and recover forgotten windows 8 password.

You can reset forgotten laptop password without login. Just like the article tells, you can get Windows Password Genius Advanced to create password reset disk. Then you can remove or reset laptop forgotten password with it. At last, you can login your laptop without password.

I will recommend Windows Password Genius Advanced, because laptop users can burn a password reset disk with it easily on another accessible computer, and then take the reset disk to remove or reset all Windows system password. Moreover, you can create new administrator for locked laptop when you are locked out of it.

To reset the password in windows, you will first need to boot the computer into safe mode. Hold F8 as the computer boots (Before the OS loading screen) and select the "Safe Mode" option (Not "Safe Mode With Command Prompt" or "Safe Mode With Networking") The computer should then boot up, but there should be an additional "Administrator" account. Log in to this account (There shouldn't be a password, but if there is, try "admin") and navigate to the User account panel in control panel. From there, select your account name, and select the "Remove Password" option. This should clear the password for your account. Shut the computer down, and reboot like normal. Your account should have no password.

If you want to keep your OS and data safe then they best way to fix this issue by taking the motherboard backup battery out and put it back using following steps:

You need to open the lower black panel apart for this you can follow the online YouTube tutorials. Once panel is taken apart then you will see a small battery cell connected with 2 red and black wires via jack. Take this jack off to disconnect the battery for about 10 mins then put it back and try turning on your pc. This shall reset your BIOS passwords etc and then you would be able to login in to your PC.

I had the same issue with my old Dell computer which I used it less frequently in last year. The funny thing is that I successfully reset the password with a bootable USB drive which had a GUI program burned into it. Then insert USB into my locked computer and set the admin password to blank.

If you reset the computer and turn it off when trying to turn on. when you turn it on agen, a error message will pop up alowing you to mess with the fills. try net user(user name here) *. then you will be asked the password. press enter twice the go to login.even if you type in the correct password, it will not work. just press login or the arrow. Do not press enter! find and change the password when you can. it will not ask you for the password to change it. normaly it does. you shold change it because if you dont when you log out, you wil lhave to do all of this agen.
